  • Quick addition to the thread.
    Recently installed the cartridge emulators in my baby Honda and the forks are now brilliant.

    A huge improvement from stock, while still really plush, they actually handle the big hits damn well.
    Xr600 shock will be dropped in soon, I assume you have to use the xr600 spring by the looks of things.

      That's very interesting, got links/prices by chance?
      It's the rear end i really want to sort out, they are so slow in their action it's painful.
      The 600 shock doesn't just drop straight in does it, don't you have to revalve it to suit the lower weight or does the clicker range cover it?
      Maybe a lighter oil would suffice with a play of the clickers too?

        • The ol girl got a bit of a makeover recently [the bike not the missus] after it had clocked up about 70 odd hours on the new ring set that i put in.

          The new rings didn't last, i can only assume they are the same shite quality as what comes with them stock. A bit before Easter it started blowing fat and ended up getting pretty bad.

          I decided to go for an oversized forged Wiseco, it took ages as no one on the planet had stock of any brand in an oversize so i had to wait from some to get made.

          In the end a late night purchase was done incorrectly and i ended up with a stock sized [65.5mm] high comp [11-1] forged unit from Wiseco, the mistake wasn't realised until i took the barrel to the machine shop to get it drilled out to a larger size.
          Whilst there i dropped the piston onto the barrel and it fell in.

          I looked into returning it for the one i wanted and it was possible but there was a lot of fkn around to be done and i had a crf230 donk in exploded form across my workshop which tends to hold up other jobs so i did an accurate measure up of the bore.

          It was just under spec for the forged unit, so with a bit of a hone which got it spot on i decided to just use it.
          Ring end gaps were checked and found to be perfect too.

          Some spanner spinning was done and last w/e we run it in out at Yack.

          Goes great, pulls a lot harder right across the whole rpm range, jetting is slightly out even after playing with it a bit but it's close enough to take out again for a proper ride to see exactly where it is at.




          While the 230 was on the operating table i decided to eliminate one of my peeves with it which is the rear brake pedal that i seem to be forever straightening out so i fitted a folding tip:

          Sick of this?

          Get one of these

          One of these

          These are handy too

          Measure things up

          Draw lines anywhere randomly, it's fun and keeps everyone wary
          Jayson in uniform Crf230 brake pedal mod 009.jpg

          Cut stuff until you end up with this
          Jayson in uniform Crf230 brake pedal mod 010.jpg

          And this, i changed my mind on what dimension i was going with so had to adjust the tip to suit

          After some shocking treatment you may end up with this

          Then it looks like that

          A worthy way to spend 40 minutes.

            • I used the race tech gold valves in my front end. These are available from their website and ebay sellers.
              Rear end I haven't had much luck with, the xr600 shock has a completely different (and stiffer spring) so is not a bolt in job by any means.

              It's frustrating there's no details about what springs people are using as the rear end is definitely an issue.

              I just stumbled on what seems like an awesome carb swap the other day. Stock 30mm xr250 carb using the crf 230 needle. Apparently the carb is identical just 2mm bigger and it works very well from the get go.

              Anyone done it? I've very keen to give it a go.

              • Nice info Hoppy, shame i've just about sold the 230.

                It hasn't actually even been ridden since i did the brake pedal mod above

                I'll pass on the info about the 600 shock to someone that is about to do it, and the carby info.

                Do you recall what mj and pj were in the 250 carby?

                • Pilot jet was 45, main anywhere from 120 - 132.

                  I think the yanks seem to run bigger jets than us for the most part, I was going to stick on the lower side of this.

                  Using the earlier crf needle is apparebtky the hot ticket, on the 4th clip it's good, the later model 2 position clip won't work well.

                  I'm much more excited about this carby conversion than adding an FCR (if you could ever get one to fit) or a pumper carby. One of the things I love about these older air cooled machines is their really tractable, progressive with great bottom end. Putting on a more modern high performance carb could easily make them too snappy which would be a shame.

                  Over the next month I'm going to have a look at the rear shock and this carb conversion, next update should be a bit sooner than my last.

                  • Some information for anyone wanting to put an XR600 shock in they're crf230.

                    Despite the info from the yanks (who must be regurgitating what they've read) it IS NOT a bolt in mod.

                    The xr shock (mine is an 89 model) is around 10mm shorter, with both shocks being so short, this makes a massive difference.
                    If you bolt it in, the bike will be sitting an inch and a half lower and it's clear on full droop things aren't right.

                    I'm currently looking at options to fix this, one is adding an extension to the actual shock, the other is adding an extra mount on the frame, 10mm or so lower from the orginal point.

                    It's hard to believe there is so much talk out there about this conversion, yet no one mentions the difference in length. I noticed it as soon as I compared the shocks but threw it in anyway just to make sure nothing magic happened once in there.
                    Nope, she's clearly too short!

                    • Straight bolt in, not!

                      Good news is that if I drop the top mount down 15mm on the crf frame I still shouldn't have any issues with travel, as the xr600 shock has a much longer throw.

                      • Well as it turns out the stockie is rebuildable.

                        If you can get in there to do seals etc then surely the slow damping rate could be sped up a bit, sure there would be no adjustability externally still but at least it would cope with higher speed hits and maybe not send you OTB.

                        Fitting up a 600 shock sounds like heaps more hassle, worth it if you get it to work but for kids that are getting faster than the stock shock can cope with then a 'simple' rebuild and mod may suffice.

                        • I see welding a tab 15 - 20mm lower on the top mount to fit the xr600 shock easier than rebuilding the stock one.

                          Only as I have plenty of scrap steel and a mig on site, if you were paying someone it would be a hassle.

                          One idea I'm flirting with for the xr600 shock is extending that mount even more to increase the travel a little, maybe 20-30mm.
                          I'll do the measurements next week as it may not work but I figure it would be another minor benefit with this upgrade.

                          • What about ground clearance once you go through 330mm? of travel?

                            Or does it only go out to a bit under 300 with the increase you are talking about?

                            Stock is 250-270 yeh but the 600 shock is longer?

                              The plan was to try to add 10-15mm each way, which would be 20-30mm in total.
                              Just an idea at this stage, I'm thinking the more minimal the increase the less likely I'll have issues with seat height and ground clearance.

                              I'm gojng to put both shocks back in without springs and run them through their travel with the 600 mount point simulated in different positions.

                              • So would you recomend installing racetech emulators over upgrading to larger shocks?
                                Springs in my wifes are crap. If you sit on it and drop the clutch to lift the front end you can hear the forks make a bang as it fully extends. Is this normal? Ive added washers for more pre load already and didnt do much.
